Risk slicing will also play a role when driverless cars are part of a car-sharing service, as drivers don’t rely on autonomous features for the same amount of time.

Finally, driverless cars will likely reduce risk to varying extends, which BLG said would “complicate underwriting.”

“It is possible that insurance policies will provide a base level of insurance, with a higher or lower premium charged on the basis of each trip or on the basis of the insured’s driving habits generally,” BLG wrote in the report. “In fact, policies where premiums adjust according to the operational habits of drivers, as determined and reported by in-vehicle sensors, already exist.”
